FAQ

What is "data after the image end"?

Bytes appended after the JPEG end marker or the PNG IEND chunk. Viewers ignore them, but they travel with the file and can carry a hidden payload.

Is any of this visible in a normal photo viewer?

No, viewers show pixels only; the metadata travels silently with the file.

How do I clean it?

Use the EXIF remover, which deletes the metadata segments.
